To aZZ whom t may concern.'

Be it lrnown that I, l/VILLIAM O. EWINGER, a citizen of the UnitedStates, resident of Burlington, in the county of Des `Moines and Stateof Iowa, have made a certain new and useful Invention in NaturalTater-Cooling Devices; and I declare the following to be a full, clear,and exact description of the same, such as will enable others skilled intheart to which it appertains to malte and use the invention, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specication.

Figure l is a side view of the invention, partly broken away.

Figure 2 is a detail central longitudinal section of the tubularcasing.`

The invention has relation to means for furnishing a continuous supplyof cool water without the use of ice or artificial refrigeration,applicable to any water system wherein there is a head or pressure ofwater, and capable of furnishing a continuous flow of water at all timesat a temperature of about 65 degrees Fahrenheit without any attentionwhatever after the irst installation. @ther advantages or objects willapear.`

The invention consists in the novel construction and combinations ofparts, as hereinafter set forth.

In the accompanying drawings illustrating the invention, the letter Adesignates a supply or service pipe of a water system, such for instanceas that of a city or town having a suiiicient head or pressure of waterto supply the same to the upper as well as the lower doors of tallbuildings; B is a vertical pipe of iron or other metal, extendingdownwardly to a depth suflicient to cool water in the lower part oflsaid pipe to a temperature of about 65 degrees Fahrenheit, 'andextending upwardly to near the surface of the ground or oor II, saidpipe being usually of 35 feet in length approximately, and being at itsupper portion provided with a T-joint B wherein the end of the pipe A isthreaded, and at its lower end with a plug N.

A plug A is threaded into the upper end of the vll-joint B", and has anupper reduced aperture, wherein is threaded a vertical'pipey C whichextends downwardly within the pipe B to near the bottom thereof, thediam i eter of the pipe C being suflicientlysmaller than that of thepipe B to leave an annular water chamber yc between the two pipes and atthe lower portion of the larger pipe, said chamber being incommunication with the pipe A, and being thereby kept filled with water,a suitable valve Dbeing provided in the service pipe to cut off thewater supply or to regulate it as may be desired. l 1

The upper portion of the pipe Bincluding the T-joint B, the plug A', andthe valve D, are located in a tubular pit or well E, provided with acover J ,and 'are thereby made accessible at all times for examinationand repair, should' such be needed.

The pipe c is provided with a bend or bends o, extendin horizontallybeneath the ground or floor I to insulation or nonheat conductingvertical tubes or casings H, ex-` tending from the floor l upwardly toall or any of the floorsr of a building, and wherein provided with avalve F, and a suitable drinking fountain 'or other means of obtainingthe cool water for drinking purposes .and

designated G, the adjustment of the valve F controlling the supply ofwater to said fountain.

rEhe invention is found in practice to work satisfactorily and tofurnish an economical supply of cool water, at a temperature which isgrateful `and preferable to that of ice water. v

This invention .twill supply cool i water above. the supply source to aheight of 20 feet for every 79u; pounds hydrostatic pressure.

I claim `A water cooling device, comprising inner andl outersubstantially concentric vertical pipes spaced apart from each other andone of which is an inlet and the other an outlet pipe and both of whichare embedded in the ground, an enlarged tubular casing Vembedded in theground and 'inclosing the upper ends of the said inlet and outlet pipesland being comparatively short, and inlet and outlet feed pipes connectedto said inner and outer vertical pipes Within said enlarged Casing, thelatter being provided with a removable cover, and said inlet feed pipebeing provided with a, cut-oil' valve loomed Within said enlargedcasing.

ln testimony whereof l affix my signature in presence of two Witnesses.
